If you find black or grey spots hindering your vision from time to time, you may be afflicted with eye floaters – an age-related condition wherein “floaters” appear in your vision and drifts around whenever you try to shift your attention from one point to another. Eye floaters happen when the vitreous inside your eyes becomes more liquidated, prompting fibers to clump and form retinal shadows – thus hindering your eyesight with objects that appear to float right before your eyes.
Causes and risk factors for eye floaters may include any of the following:
- Age. Vitreous in the eyes tend to liquify as one person gets older. This liquefaction process tends to create clumps in the retina, thus forming eye floaters.
- Retinal tears or eye inflammation. Sagging within the vitreous may tear the retina which may then cause fluid accumulation behind it. Sighting of eye floaters is in fact a common symptom among individuals with retinal breaks.  Alternatively, debris due to an eye inflammation may cast shadows on the eye, causing eye floaters to appear.
- Bleeding, surgeries or medication. Bleeding may cause blood to be seen as floaters. Likewise, certain eye surgeries or medications may produce bubbles that can then be interpreted by the eyes as eye floaters.
- Nearsightedness or myopia. Nearsighted individuals tend to see eye floaters compared to individuals without such condition. For individuals with myopia, liquefaction of the vitreous gel in the eyes tend to be accelerated, thus making it more likely to see clumps or shadows. 
As to whether or not eye floaters are common among older people, Posterior Vitreous Detachment or PVD usually happens among individuals who are around 60 or 70 years of age. With such condition, eye floaters tend to be noticed more by older age groups than younger ones
But the question would be how long do eye floaters last? Usually, these clumps or shadows are not long consequences, however can be a symptom of detachment in the retina.  Therefore, it is essential to see an eye specialist in case of discomfort or if the problem persists long enough to induce day-to-day problems.
For natural and immediate treatment of eye floaters, it’s a good idea to get yourself a high quality hyaluronic acid supplement like IALUTEC 100% Pure Hyaluronic Acid. Not only will it replenish the the lost hyaluronic acid, but it will also help lessen the occurence of eye floaters.
